4 Series 40A 18650 Lithium Battery Protection Board 14.8V 16.8V with Balance for Drill Motor Lipo Cell Module

The 4 Series 40A 18650 Lithium Battery Protection Board 14.8V 16.8V with Balance for Drill Motor Lipo Cell Module comes with recovery function. 
AUTO Recovery and Integrated 10 low load resistance MOS tube.
It provides a continuous discharge of 40A, 100mA balanced current, for electric drill/sprayer/LED lights/low power inverter. (If the cooling environment is not good, please reduce the load current use).
Charging voltage can be range between 16.8V to 18.1V
The board operates smoothly with Continuous charge current of (upper limit): 20A.
The balanced version is suitable for starting current below 80A, power 135W below the drill (with balance).
The Board which can be easily installed in a compact size or on battery bundle itself.

Note:

Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit. 
4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use it in series.
